I recommend, great price on amazon

Bought it Tuesday for my son’s birthday. It is now Friday and he is bored with it. He no longer plays with it and it is just thrown in a corner somewhere. Also it is a little expensive.

My grandson really loved this little guy. It was a great Christmas gift.

I bought the black sphero Ollie for my 13 year old son for Christmas and he is sooooo in love with it. I’m super impressed with how entertaining the sphero Ollie is. Literally keeps all of us in the family entertained for hours. Very happy with the Ollie purchase.
